This station was working as a station before it went dead. In other words, "no, it's not hacked up."
Can anyone tell me for sure where the service jumper - JU1 is. I found 'a' JU1 on the SSCB board, but it seems relatively hidden for a service jumper. Also, when I move it's position I get an error on the LED display, then the station resets.
